一个或多个节点未连接到两个集群交换机

在使用Cisco交换机的MetroCluster IP配置中，即使与交换机的所有连接均已联机，也可能会出现以下HM警报：

Cluster-A::*> system health alert show
Node: Node-A1
Resource: Node-A1
Severity: Major
Indication Time: Mon May 10 17:59:20 2021
Suppress: false
Acknowledge: false
Probable Cause: One or more nodes are not connected to both cluster switches.
Possible Effect: If one cluster switch fails, "Node-A1" might lose
access to the cluster.
Corrective Actions: Verify that the switch "Switch_A1" is connected to the node "Node-A1".

device-discovery输出中缺少一个交换机：
